While other manufacturers may require up to 3.1″ insulation over combustible decks, RESISTA polyiso has a UL Class A rating for fire resistance. The double coating of non-organic facing material on both sides of the insulation board also meets ASTM D 3273 standards for mold resistance.

In addition to fire, wind and environmental protection, RESISTA polyiso is a environmentally sustainable product that contains recycled content and can contribute to overall LEED® certification for energy optimization and material resource credits.
